Unfortunately you need to remove the barrel nut. There is nothing else holding the muzzle nut in place. You probably just need to "crack" it loose. Stick the gun in a vice so you then have both hands on the circlip pliers. Alternatively, you could make a tool from a hex socket. Grind / cut it to make some (maybe two) pins to fit the muzzle nut. Then you can fit a larger bar for more leverage. Good luck!

Ok,
Thanks Jimmie,

I’ll mak a decent tool, circlip pliers are too unstable.

Cheers,

I managed of with circlip pliers. I bought some heavy duty ones from Screwfix. There are four in a case. I originally bought them for work on another airgun and had to grind down the ends on one for it to fit. They are very strong pliers. The trick is to use the 90 degree angled pliers and make sure they are deeply inserted into the holes and keep one hand pressing down at the muzzle nut and the other on the handles to turn the nut.

I broke a pair of circlip pliers doing it so used thicker electricians pliers.

I have however made a tool for similar applications, it consists of a bar with holes down it with bolts going through it and the end of threads removed so as not to mark the part. Ideal pepperpot type dump valves too.

It worked!

I did exactly as you said above, they were the heavy duty circlip pliers, which I ground down a bit for a snugger fit.

I've been wanting to get this apart for ages, finally put a new seal in and it's upped the power a bit so that's good.

Thanks for the advice.

Do these take a standard sized spring? would be nice to fit a new spring too.


Cheers,

Matt.

No idea about the spring. Best you can do is measure outer diameter, wire thickness and number or coils per inch and see if you can find something similar. Coils per inch is important otherwise you will not be able to compress the spring down enough to cock the pistol.

I took it down the club at the weekend and it's shooting much sweeter with the new seal, and very, very accurate.
Think I'll leave the spring for a future project but good to know how to do it.

Such a fun pistol to shoot!

Thanks for the advice,

Matt.
